|Hunebed D17 at Rolde|
Today it's all about hunebedden, 52 of which stand in Drenthe (two more in Groningen). They are the remains of 5000-year-old dolmens, or burial tombs. At the Hunebed Center, a museum dedicated to the ancient monuments, I learned that they were built at the dawn of the Neolithic era and first excavated in the 19th century. It is believed that the granite boulders used for these dolmens arrived with the glaciers from Scandinavia during the Ice Age.
